Core Responsibilities

Primary Functions

Expertly operate various grinding machines, including surface grinders, cylindrical grinders, and specialized blade sharpening equipment, to sharpen and recondition industrial knives and blades.
Precisely set up grinding machines by adjusting wheel speeds, feed rates, table angles, and machine stops to meet demanding product specifications and tolerances.
Carefully select and mount appropriate grinding wheels, dressing and truing them as needed to maintain optimal shape and cutting effectiveness for different materials and finishes.
Systematically inspect incoming dull or damaged blades to accurately diagnose the extent of wear, chips, or damage and determine the most effective method for sharpening or repair.
Perform high-precision grinding, honing, and deburring operations on a variety of materials, including high-carbon steel, stainless steel, and tungsten carbide.
Utilize precision measuring instruments such as micrometers, calipers, protractors, and optical comparators to meticulously verify blade dimensions, angles, and surface finish against blueprints and quality standards.
Conduct regular, in-process quality control checks throughout the sharpening process to ensure absolute consistency and prevent any deviation from specifications.
Diagnose, troubleshoot, and resolve issues with grinding machinery, performing routine preventive maintenance to ensure optimal performance, safety, and equipment longevity.
Maintain accurate and detailed records of work performed, including machine settings, blade types, and maintenance logs for full traceability and process improvement analysis.
Adhere strictly to all company safety protocols and OSHA guidelines, including the proper use of personal protective equipment (PPE) such as safety glasses, gloves, steel-toed boots, and respirators.
Manage and maintain an inventory of grinding wheels, coolants, and other essential consumables, reporting replenishment needs to the supervisor to prevent stockouts and production delays.
Interpret complex technical drawings, blueprints, and work orders to fully understand the specific geometric and material requirements for each grinding job.
Collaborate effectively with production and maintenance teams to schedule blade changes and sharpening, strategically minimizing equipment downtime and production interruptions.
Meticulously clean and maintain grinding machines and the surrounding work area to ensure a safe, organized, and highly efficient environment.
Perform static and dynamic balancing of grinding wheels to prevent machine vibration and ensure a superior, high-quality surface finish on all sharpened blades.
Skillfully adjust and set up fixtures, magnetic chucks, jigs, and holding devices to securely position blades for accurate and safe grinding operations.
Monitor the entire grinding process, listening for unusual noises and observing machine operation to proactively detect potential malfunctions or safety hazards.
Handle and transport sharp, heavy, and often delicate blades with extreme care and proper technique to prevent personal injury or damage to valuable assets.
Develop and refine grinding techniques for new or unusual types of blades and materials, contributing to the team's continuous improvement of quality and efficiency.
Immediately report any non-conformance, quality issues, or safety concerns to the shift supervisor or quality department for prompt corrective action.
Assist in the hands-on training and mentorship of new or less experienced operators on proper grinding techniques, machine operation, and critical safety procedures.
Actively participate in continuous improvement (Kaizen) initiatives, providing valuable feedback and suggestions to enhance workflow, safety, and product quality.

Secondary Functions

Support ad-hoc sharpening requests from the Research & Development or maintenance departments for special projects.
Contribute to the organization's equipment maintenance strategy and preventative maintenance schedule.
Collaborate with the engineering team to test and provide feedback on new blade materials or grinding wheel compositions.
Participate in daily production meetings, safety huddles, and planning sessions within the manufacturing team.
